Cutoff values of major surgical complications rates after gastrectomy
No full textGastric cancer is one of the most frequent cancers worldwide, and surgical resection remains the mainstay of the therapeutic pathway. Gastrectomy for cancer is still performed in many hospitals, and centralization remains limited to a small number of health systems. Morbidity and mortality after surgery for gastric cancer are surprisingly high. However, while mortality is obviously defined, major morbidity definitions still present some critical points. The aim of this study is to underline the need for universally accepted definitions of major complications and to describe the research agenda of a multicenter, European-based, prospective project launched by the European Chapter of the International Gastric Cancer Association (IGCA), with the goal of providing a list of complications related to gastrectomy for cancer with their definitions

Automatic conflict analysis and resolution of traffic filtering policy for firewall and Security Gateway
No full textFirewalls and Security Gateways are core elements in network security infrastructure. As networks and services become more complex, managing access-list rules becomes an error-prone task. Conflicts in a policy can cause holes in security, and can often be hard to find while performing only visual or manual inspection. First, we have defined a methodology to systematically classify the severity of rule conflicts; secondly, we have proposed two different solutions to automatically resolve conflicts in a firewall. For one of them we found an algebraic proof of the existence of the solution and the convergence of the algorithm, and then we have made a software implementation to test it. © 2007 IEEE
Multi-originator data dissemination in VANETs
No full textIn the framework of the Vehicular Ad-Hoc Networks we propose HBEB (Hybrid Based Election Backbone), a distributed algorithm designed to form multiple backbones of vehicles in charge of propagating data in the VANETs in a fast and efficient way. Differently from other clustering approaches we leverage the ETSI Geonetworking recent standard to form and disseminate data in the backbones. We show that the formation of these backbones is quite easy to be implemented while their use enhances the dissemination performance in an urban scenario

Both species are only known from a very few specimens, mostly females. This did not allow a sufficient evaluation of the intraspecific variability, thus the distinction is based, as well as on a different pattern of colouration that I usually do not consider to be sufficient, upon a few other characters which, although weak, I judged to be consistent enough to allow the species to be distinguished. One of these characters is the lateral pronotal carina (Fig. 28), which is rather unusually extended for the whole lateral pronotal length, differing from most other species where it never reaches the anterior pronotal margin (Fig. 29).</p> <p> In order to make an appropriate comparison of the same sex, the holotype of <i>A. simandli</i> <b>sp. nov.</b> was compared to a fresh, reared female of <i>A. magnifica</i> which had itself been previously compared with its holotype. The character states that differentiate the two species are listed below:</p> <p> <b> <i>Anthaxia (Anthaxia) simandli</i> sp. nov. <i>Anthaxia (Anthaxia) magnifica</i> Bílý, 1983</b> Body (Fig. 1) stout, about 2.5 times longer than wide; head Body (Fig. 4) slightly slender, 2.6 times longer than wide; and pronotum red, elytrae blueish-green head and pronotum green, elytrae red-purple Head: sculpture of frons (Fig. 21) very densely foveate- Head: sculpture of frons (Fig. 22) more sparsely foveolate reticulate</p> <p>Antennae (Fig. 3): scape 2.9 times longer than wide Antennae (Fig. 6): scape 3.1 times longer than wide Pronotum (Fig. 3) 1.6 times wider than long; lateral carina Pronotum (Fig. 6) 1.5 times wider than long; lateral carina (Fig. 28) complete, extending from laterobasal angle to (Fig. 29) incomplete, disappearing at 3/4 of lateral pronotal anterior pronotal margin length</p> <p>Elytral sculpture rough; lateral groove homogenously deep Elytral sculpture smoother; lateral groove flat on posterior 1/</p> <p>3</p> <p>Ventral surface (Figs. 2, 30): posterior end of central Ventral surface (Figs. 5, 31): posterior end of central metasternal suture distinctly divergent; metasternal sculpture metasternal suture not divergent; metasternal sculpture more distinctly, densely imbricate-areolate sparsely imbricate-foveate</p> <p>Legs: protibial carina of outer edge (Fig. 52) irregular but Legs: protibial carina of outer edge (Fig. 51) irregular, not emarginate distinctly emarginate apically</p> <p>Anal ventrite (Fig. 34) 1.6 times wider than long, lateral Anal ventrite (Fig. 35) 1.5 times wider than long, lateral margins straight, apex more deeply notched margins weakly arched, apex feebly notched</p> <p> <b>Bionomy and distribution</b>. The only known specimen of <i>A. simandli</i> <b>sp. nov</b>. is a female found in a narrow valley (Fig. 60) about 25 km southeast of Dorud, in the Lorestan province. According to this single topotypical locality, this new species is tentatively classified in the W-Iranian endemic chorotype (Vigna Taglianti <i>et al.</i> 1999).</p> <p> The specimen was caught on a decorticated area of a trunk of <i>Salix</i> already showing a number of large exit holes, probably of Cerambycidae (Simandl, pers. comm.), and it was apparently probing the wood, in search of a suitable place to lay eggs. This behaviour suggests that <i>Salix</i> most probably represents a host-plant for this new species, as this is a host for its closest relative <i>A. magnifica</i>. Since the type of riparian habitat in which it was collected is commonly found in the whole country, and is not well studied, I expect this new species to be more common than a single record would suggest.</p> <p> <b>Etymology</b>. <i>A. simandli</i> <b>sp. nov.</b> is dedicated to my friend Jiri Simandl (České Budĕjovice, Czech Rep.), the first collector of this magnificent species.</p>Published as part of <i>Baiocchi, Daniele, 2013, The Anthaxia (Anthaxia) manca (Linnaeus, 1767) species-group in Iran, with description of a new species and a new synonymy (Coleoptera: Buprestidae), pp. 455-481 in Zootaxa 3613 (5)</i> on pages 462-466, DOI: 10.11646/zootaxa.3613.5.3, <a href="http://zenodo.org/record/247248">http://zenodo.org/record/247248</a>
Patterns of beta diversity in riparian ground beetle assemblages (Coleoptera Carabidae): A case study in the River Aniene (Central Italy)
No full textWe investigated riparian ground beetle communities to: (1) identify the main environmental factors determining species composition; (2) determine whether sites with similar ecological characteristics have similar species composition as a result of local selection; and (3) provide some indications for conservation of these insects. For 45 sampling sites in the River Aniene we measured: elevation, river bank morphology, percentage of shaded area, habitat heterogeneity, sediment depth, sediment granulometry and geographic position. We then used Canonical Correspondence Analysis (CCA) to investigate the importance of these variables in structuring beetle communities and cluster analysis (CA) to identify groups of sites with similar species composition. Granulometry and elevation were the most important parameters influencing species composition. Position of assemblages in CCA space was partially similar to their groupings in CA. In particular, silty sediments hosted a homogeneous group of species (with several highly specialized elements), well separated from all other clusters, suggesting that this type of substrate exerts a strong local selection pressure on ground beetle species. Communities characterized by species associated with coarse sediments were typically found in isolated localities. Further isolation of these populations by impoundments would have a serious impact on their persistence
S-VPN policy: Access list conflict automatic analysis and resolution
No full textS-VPN gateways are today core elements in network security infrastructure. As networks and services become more complex, managing IPSec access rules becomes an error-prone task. Conflicts in a policy can cause holes in security, and often they can be hard to find when performing only visual or manual inspection. We have defined firstly a methodology to systematically classify the severity of rule conflicts and secondly we have proposed two different solutions to automatically resolve conflicts in an access list, implementing and testing one of them
Accelerated 15 mW pulsed-light crosslinking to treat progressive keratoconus: Two-year clinical results
No full textPurpose To assess the clinical and microstructural results of accelerated 15 mW pulsed-light corneal crosslinking (CXL) to treat progressive keratoconus. Setting Siena Crosslinking Center, Siena, Italy. Design Prospective case series. Methods After epithelium removal (with Epi-Clear) and 10 minutes stromal soaking with riboflavin 0.1% hydroxypropyl methylcellulose solution, all eyes had 15 mW/cm2pulsed-light epithelium-off accelerated CXL for 6 minutes of ultraviolet-A (UVA) irradiation (1 second on/1 second off), maintaining a total UVA exposure of 12 minutes at a fluence of 5.4 J/cm2. The 2-year follow-up examination included uncorrected (UDVA) and corrected (CDVA) distance visual acuities, Scheimpflug tomography, in vivo confocal microscopy (IVCM), and spectral-domain optical coherence tomography (SD-OCT). Results The study comprised 132 eyes of 96 patients (mean age 23.7 years ± 4.3 [SD]) with stage II keratoconus. The change in UDVA and CDVA was statistically significant, from 0.51 ± 0.106 logarithm of the minimum angle of resolution (logMAR) at baseline to 0.309 ± 0.074 logMAR (P =.0001) and 0.271 ± 0.144 logMAR at baseline to 0.135 ± 0.100 logMAR (P =.0023), respectively. Coma values measured by Scheimpflug analysis showed a statistically significant improvement beginning with the first postoperative month (P =.0004). The IVCM scans documented basal epithelial healing occurring 72 hours after treatment associated with the presence of subepithelial nerves. The SD-OCT scans performed in the central 6.0 mm of corneal diameter documented a demarcation line at a mean depth of 280 ± 32 μm. Conclusion The 15 mW/cm2pulsed-light epithelium-off accelerated CXL was effective and safe, stabilizing keratoconus progression through 2 years of follow-up
